RESUMO
This study sequenced the entire mitochondrial genome of Populus davidiana Dode. It was 779,361 bp in length, containing 33 protein-coding genes, 3 rRNA genes and 22 tRNA genes and 1 pseudogene, and its GC content was 44.8%. Phylogenetic analysis was conducted using 6 mitochondrial genomes from the Salicaceae and Euphorbiaceae families, resulting that P. davidiana Dode was closely related to Populus tremula and Populus tremula × Populus alba. These results will provide fundamental data for the evolutionary studies in Populus genus.
RESUMO
The complete chloroplast genome sequence of Populus davidiana Dode was determined in this study. The cpDNA was 155,853 bp in length, containing a pair of inverted repeats (IRs) of 27,571 bp each separated by a large and small single copy (LSC and SSC) regions of 84,127 bp and 16,584 bp, respectively. The cpDNA contained 130 genes, including 85 protein-coding genes, 8 ribosomal RNA genes and 37 transfer RNA genes. Phylogenetic analysis indicated P. davidiana was mostly close to Populus tremula, widely distributed in Europe and Populus tremula × alba.
